Welcome to America’s best unlimited network

Since our network is built for unlimited, you can stream, text, and snap as much as you want. All on the fastest LTE network in the nation.

Based on Q2 & Q3 2017 data. On all T-Mobile plans, during congestion, the small fraction of customers using >50GB/mo. may notice reduced speeds until next bill cycle due to data prioritization. Video typically streams at DVD quality (480p).

T-Mobile now ranks #1 in network tests.

We topped Ookla and OpenSignal’s 2017 rankings, confirming that we have the fastest, most available 4G LTE network.

Questions about coverage?

When will coverage be expanded in my area?

We are continuously evolving our LTE network and expanding into new areas. Visit
the LTE Comparison Map to review all of our planned coverage expansion for 2017.

What is Extended Range LTE?

Our Extended Range LTE signal goes 2x further and is 4x better in buildings than before. To ensure you can take advantage of the enhanced signal strength and coverage, you need a capable device.

What does my device have to do with coverage?

Not all devices have the same capabilities. Older devices weren't built to take advantage of the network we have today. For example, if you don't have a device with Band 12 (700 MHz), you won't be able to take advantage of T-Mobile's
Extended Range LTE. For more information, check out our T-Mobile
Coverage Map to see what kind of coverage you can expect where you live, work, and play with the device you're using.

I go to Mexico/Canada frequently. Can I get service there?

Unlimited talk, text, and data with up to 5GB at 4G LTE speeds throughout Mexico and Canada is included for no additional charge through the T-Mobile ONE™
plan wherever there's coverage. Note that on all T-Mobile
plans, if congested, the few customers who use over 50GB of data may notice reduced speeds until their next bill cycle due to prioritization.

How do I know in what countries I have free data and texting?

plans, if congested, the top 3% of data users (>32GB/mo.) may notice reduced speeds until their next bill cycle due to prioritization.

What will 5G enable me to do in the future?

5G mobile networks are set to enable one of the biggest tech transformations in history, with incredibly low latency, very high bandwidth and sensors capable of decade-long battery life. At T-Mobile,
we will put 5G mobility to work for our customers, like we always have with new technologies. Our focus is on all the exciting ways 5G mobility will revolutionize our lives. Click here

What solutions does T-Mobile
offer for in-home coverage issues?

We have four solutions available for residential coverage improvements. Wi-Fi Calling
is self-service, and can be enabled and disabled on your phone directly. For the other solutions, Wi-Fi CellSpot Router, 4G LTE CellSpot®, and 4G LTE Signal Booster, customers should call T-Mobile Care
or visit a T-Mobile
store to discover which solution is best for you.

What is Wi-Fi
calling?

Wi-Fi
Calling gives you the ability to make and receive calls and SMS/MMS over Wi-Fi
, just as if you were on the network. This is particularly helpful in areas where you have weak or no cellular signal (basements, rural areas, etc.), but have a strong and reliable Wi-Fi
signal. Wi-Fi Calling
also enables you to call back to the U.S. from anywhere in the world for free! Unlike our competition, all of the T-Mobile
handsets in retail have Wi-Fi Calling
built into the handset.
